Recurrence of pulmonary intravascular bronchoalveolar tumor with mediastinal metastasis 20 years later.

ABSTRACT

Pulmonary intravascular bronchoalveolar tumor (IVBAT) also recognized as pulmonary epithelioid hemangioendothelioma, is a rare malignant vascular tumor of unknown etiology. IVBAT is a tumor of multicentric origin and the lungs are rarely involved, with only about 60 cases of pulmonary IVBAT described in the literature. The prognosis is unpredictable, with life expectancy ranging from 1 to 15 years. We report an unusual case of pulmonary IVBAT that recurred in the lung with metastasis to the mediastinum.
